The two large double pyramids (octahedra) closer to the Milky Way.
(Battaner & Florido, 1997)

Imagine that each galaxy is like a speck of sand in the universe. Imagine that the universe itself is filled with an energy source that is vibrating, and has certain qualities that are similar to a fluid. In the unified model, pressure currents throughout the universe would cause these galaxies to naturally drift into alignment with the borders of a matrix of geometric patterns.

In this case, however, the identification of real double pyramids (octahedra) is so clear and the network is so noticeably well-defined that a direct inspection is straightforward. (E. Battaner and E. Florido, 1998)
